VETERINARY ECRASEU R.

SPECIFICATION forming part of Letters Patent No. 495,668, dated April18, 1893.

Application tiled October 8, 1892. Serial No. 448.190. (No model.)

T0 a/ZZ whom it may concern.-

Beit known that I, ALFRED FTE, a citizen ot' the United States ofAmerica, residing at Horton, in the county of Brown and State of Kansas,have invented certain new and useful Improvements in Ecraseurs, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention-relates to ecraseurs; and has for its object theimprovement of the instrument in such a manner that by one operation thecord will be severed and the end pressed and bruised so as to preventbleeding.

My invention consists in applying to an ecraseur of the usual form asecond member for the purpose above stated.

In the accompanying drawings: Figure l is an elevation of my improvedinstrument looking from the side. Fig. 2 is an elevation looking fromthe edge. Fig. 3 is an axial section; and Fig. 4 is an end view showingthe slotted guide which forms the cutting edges with the hooked blades,the latter being removed.`

Referring to the drawings, A indicates the main body or stationarymember of the instrument; b a blade terminating at one end in the hook Cand at the other in the screw C', which passes freely through the headh', and is provided with a handle d, the central portion of which isperforated and threaded forming a nut to tit the screw shank C; e is asecond blade which is also provided with a hooked end e and with twothreaded studsf, f which pass through a slot g in the body A and throughslots h, h in the member b where they are provided with thumb nuts m,fm. The hooks or blades c, c, pass through slots in a guide k the edgesof which are made to co-operate with the hooks in severing the cord. Theslots h, h are made larger in the center so that when the nuts areloosened and turned lengthwise of the instrument, the parts may beeasily separated. When the instrument is assembled, the blades areadjusted so that when the hook C will have advanced far enough to havecut the cord, the hook e will have caught it near the severed end and bypressing it tightly will further bruise and -strument is ready for useand the parts are held to position by means of the nuts m, m.

The operation of the instrument is as follows: The handle n is turneduntil it is far enough back on the screw C to allow the hooked blades c,c, to protrude entirely through the guide k, when the testicle cord isplaced within the hooks and the blades are drawn back by means of thehandle n until the cord is brought tightly against the guide la, whenthe handle is rapidly turned until it strikes the head b', when it isturned gently until the cord is severed and the blade e has crushed theend, when it is relaxed, as the operation has been performed.

\ Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a surgical instrument of the class described, two operatingmembers having hooked ends and an intermediate body provided with alongitudinal slot, the operating members being connected through theslotted body; one member being provided with threaded projections andbinding screws, and the other with elongated openings to co-operatetherewith, and an operating handle, substantially as described.

2. In a surgical instrument of the class described, two operatingmembers adapted to first sever a ligament-and then crush the end toprevent bleeding; said members being connected and capable oflongitudinal adjustment in relation to each other, a body intermediateof said operating members, adapted to support and guide the same and toco-operate in severing and crushing the ligament; one member beingprovided with a threaded shank and an actuating handle substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
